Abstract
A display apparatus includes a base substrate, a data line to transmit a data signal, a gate line disposed on the base substrate and insulated from the data line, and a pixel electrically connected to the gate line and/or the data line via a thin film transistor. At least one of the data line and the gate line includes a lower conductive layer and an upper conductive layer. The lower conductive layer includes a zinc oxide doped with a doping material. The upper conductive layer is disposed on the lower conductive layer and includes a copper, and the upper conductive layer includes crystals in which growth directions are dispersed by the doping material.
